Memory latency and bandwidth are progressing at a much slower pace than processor performance. In this paper, we describe and evaluate the performance of three variations of a hardware function unit whose goal is to assist a data cache in prefetching data accesses so that memory latency is hidden as often as possible. The basic idea of the prefetching scheme is to keep track of data access patterns in a Reference Prediction Table (RPT) organized as an instruction cache. The three designs differ… CONTINUE READING
